Abstract

This paper presents the throughput and delay analysis of a packet-switched CDMA network based on the hybrid direct sequence (DS)/slow frequency hopping (SFH) spread-spectrum multiple-access (SS MA) technique with Q-, B- and D-PSK modulation. We consider multipath and multiple access interference and we consider the indoor radio channel to be of the slow Rician fading type. The performance is evaluated for a given bit rate, delay spread and bandwidth. The effect of forward error correction (FEC) and diversity techniques, such as selection diversity and maximal ratio combining on the performance is also investigated
